VOIP (P5)

VOIP is a Voice Over Internet Protocol, a category of software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets such as something like Skype.

VOIP gives to people things that companies make people pay extra for such as:

Caller ID

Call waiting

Call transfer

Repeat dial

Return call

Three-way calling

Advantages:

• It gives you access to free application that you would usually have to pay for
• Easy to use
• You can integrate it with an existing phone connection
• You can send messages and phone someone at the same time

Disadvantages:

• You can loss service during outings
• With VOIP emergency calls, it is hard to locate you and send help in time
• Some times during calls, there may be periods of silence when data is lost while it is being unscrambled
• There can be moments when it may lag and make it so that it is hard to understand the other person!

Name of applications	Advantages	Disadvantages
Skype	You can directly talk to the other person and you can send messages to other people at the same time.	The quality of the video chat can be bad when in a low connection area. Not everyone has Skype on their laptop
Facebook	You are able to talk to multiple people at once.	You aren’t able to video chat people or just generally talk to them other than sending messages
Email	You are able to send attachments such as documents and images.	Sometimes it takes a while to get a reply from someone because they may not check them email regularly.

Skype is the better of the three applications because you are able to do what the other applications can do and more. It is able to talk to people individual people or a group of people using video chat as well as being able to message people individually or in a group. Whereas Facebook and email you are only able to sent messages which sometime you have to wait a while to get a reply whereas Skype you generally get a reply quickly.
